In linear PE mode the early and late depth stage do not only disagree about the cache layout, but they seem to fundamentally disagree about the buffer layout. When Z was written via the late stage, early tests always show spurious zfails, even if they are not in the same draw call. Cache flushing and pipe stalls don't help in that case. The only option to get reliable Z tests with linear render targets is to move all Z handling into the PE stage. Even when early Z writes are possible, we don't know if any other draw to the same surface needs late Z handling, so we must never use the early stage.
